EUGENE L. KEYES, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that I, EUGENE L. KEYEs, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain Improvements in Lasting-Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to lasting machines and it is herein shown asembodied in an end lasting mechanism of the bed type of lasting machine.

The illustrated machine comprises a support for the last and endembracing wipers the edges of which are shaped to fit the contour of thelast. These wipers are closed about an inverted last below its bottomand are raised in rubbing contact with the upper on the side faces ofthe last to wipe the upper up to the edge of the last. When the edge isreached the wipers are closed over the last bottom to wipe the upperinwardly ver the margin of the innersole and lay it down thereon inposition to be fastened.

A very important feature of this invention consists in the combinationwith a lasting instrumentality that has such an upwardly wiping andinwardly overlaying movement of means for limiting the upward movementand determining the plane of the inward movement.

A further feature consists in a feeler to find or determine the plane ofthe shoe bottom and which is arranged to determine, with relation tothat plane, the plane in which the overwiping movement shall take place.

The utility of this invention will be recognized in the fact that thewipers after having rubbed or wiped the stock up the side face of thelast to its edge are expected to force the surplus or fullness ahead ofthem into lasted position upon the shoe bottom where it may be fastenedunder tension or in smooth condition. Unless Wipers are closed inwardlybefore they get too high they lose their grip on the upper and thefullness slacks back so that the upper is not smoothly overlaid undertension and the wipers have to be lowered and the upper wiped up again.By using a properly acting limiting stop the upward movement of thewipers can be Specification of Letters Patent.

made with certainty that the grip on the upper will not be lost.

In the illustrated machine a hold-down is employed to clamp the lastdown upon the support and prevent it from being raised by the upwardaction of the wipers. This hold-down is herein utilized as a feeler topos1t1on a stop with relation to the plane of the bottom of theparticular shoe that is in the machine and an abutment, preferablyadjustable, is arranged to engage with the stop and determine the limitof the rismg movement of the wipers and the plane of their inwardmovement.

The several features of the invention will appear in connection with thefollowing description of the machine in which they have been embodiedand will then be pointed out in the claims.

Figure l is an elevation of the toe lasting head partly in transversesection and look ing from the rear toward the front; Fig. 2 is aperspective detail of the toe lasting mechanism showing the new devices;Fig. 3 is a perspective view showing the abutment which is moved by therising wipers to engage the new stop for determining the plane 011 whichthe wiper closing movement shall take place; Fig. l is a side elevationillustrating the portion of the machine equipped with this invention.

The invention is shown in the drawings as applied to a well-knowncommercial lasting machine of the type illustrated in British Patent No.22,630/08. Reference may be had to said patent for a general descriptionof the machine thus rendering it unnecessary to describe in thisspecification mechanisms which are not particularly concerned with thepresent invention.

The frame 2 of the machine carries a rest 4 for the shoe and has a head5 sustained in a normal depressed position upon springs ('5 and capableof being elevated and also depressed by connection through a rod 7 witha treadle 8. The end embracing wipers 10 and their closing mechanismincluding the lever 12 may be like the wipers andtheir actuatingmechanism shown in said British patent. These parts are so arranged thatwith a shoe upon the support 4 the Wipers are closed to cause theirappropriately shaped acting edges to embrace the shoe be low its sole.The wiper carrying head is then raised while gripping pressure of havebeen raised high enough to permit them to close over the last bottomthey are.

closed and caused to wipe in and lay down the upper in lasted positionupon theshoe innersole, this closing movement being efiected by the handlever 12.

Attached to the rear side of the frame of the machine as shown at theright hand in Fig. 1 is a bracket 13 upon which is mounted forhorizontal sliding movement longitudinally of the machine a block 14. Arod 15 projects laterally from the rising and falling wiper carryinghead into a vertical slot 16 in said block. This arrangement allows thevertical movement of the wiper carrying head relatively to the block 14and insures movement of the block 14 longitudinally of the machine withthe wiper carrying head or with the wiper carrying plate 3 which ismounted on the head for adjustment lengthwise of the machine for longand short shoes as is customary in this type of machine. Through thehead of the block 14 extends a hold-down post 18 that has a forward andbackward sliding connection with a horizontal connecting pin 19 in thehead of a hold-down rod 20 which extends downwardly to a hold-downdepressing treadle 21, Fig. 1. The hold-down head 22 is mounted on theupper portion of the post and together with the post is normally upheldby a spring 23 which encircles the post between the block 14 and saidhead. The spring is preferably connected under torsional tension to thehead and to the block in such manner that when it is free to do so itwill turn the head in a direction to withdraw the hold-down from theshoe. The head has a laterally projectingarm upon which is mounted aforwardly 'extending hold-down finger 25. The operator "turns the head22 from the position shown in Fig. 1 to that shown in Fig. 2 and thendepresses the treadle to force the hold-down to clamp the shoe upon thetoe rest and hold the shoe down against the uplifting force of therising wipers. A friction locking device 26 is pivoted in the block 14to engage one side of the post 18 and automatically secure the hold-downin position to which it has been depressed. A spring 28 draws down onthe free end of the locking device. To lift the locking device forreleasing the hold-down a lever 30 is pivoted in the block 14 and isadapted to engage at oneend under a laterally projecting stud 32 on thelocking device. The other end of the lever 30 stands in a recess in thehead 33 of a rod 34 which is connected by a link to a bell crank 35fulcrumed on a lever 36 which extends transversely across the machineandcarries a roll that is in the path of a cam 38 on a cam shaft 40 whichalso carries other cams as shown and described in said patent foreffecting the shoe acking operation. By this arrangement the hold-clownis automatically released from the shoe in time relation with theunjacking operations by which the shoe is freed preparatory to removingit from the machine. The bell crank 35 has also a connection with a pushrod 42 the head44 of which is in position to be engaged by the knee ofthe operator for releasing the hold-down at any time selected by himprior to the unjacking operation. The hold-down head 22 has a second arm45 which, when the hold-down is in operative position, projectsforwardly over the slot 16. In the upper portion of this slot 16 ismovable by the uplifting movement of the rod 15 a slide 46in the upperend of which and projecting above the block 14 is an adjustable abutmentscrew 48 arranged to engage the arm 45 and stop the upward movementofthe wiper carrying head and the wipers. This arrangement provides thatthe hold-down shall serve as. a-feeler to ascertain the plane in whichthe shoe bottom, that is, the upturned face of the shoe innersole, islocated, it being understood that this plane will vary with thevariations in the thickness of lasts and the thickness of materials. Thearm 45 is positioned vertically in accordance with the plane of the shoebottom ascertained by the feeler 25 and constitutes a stop for limitingthrough the connections 48, 46, 15 the upward move ment of the wipercarrying head. By adj ustment of the abutment screw 48the head may bestopped immediately when the wipers have reached an elevation at which,while continuing their hold upon the upper, they can be forced inwardlyover the margin of the innersole. This arrangement avoids the liabilitywhich has heretofore existed that the operator wouldrraise the wiperstoo high before closing them and thus fail to wipe in all of thefullness in the stock which he has gathered in'wiping up the side facesof the last.

Having explained the nature of this in vention, I claim as new anddesire to secure by Letters Patent of the United States: 7
